“Both demand and supply have steadily increased over the last several weeks,” said AAA Northeast’s Mary Maguire. “The jump in demand combined with a small increase in supply pushed the national gas price average two cents more expensive on the week to $2.88. This is the largest one-week national jump we’ve seen in five weeks.”
